Original MANN‑FILTER Interior Filter CU 4007 – For Passenger Cars

The MANN‑FILTER CU 4007 is a premium cabin air filter designed to deliver clean, healthy air inside the vehicle’s interior. Engineered with advanced filtration technology, it protects occupants from dust, pollen, pollutants and airborne contaminants while maintaining optimal airflow.

Key Features

• High‑Efficiency Filtration: Utilizes a multi‑layer media system that captures particles as small as 0.5 µm, ensuring superior protection against allergens and irritants.
• Low Pressure Drop: Maintains smooth airflow to the HVAC system, preventing any reduction in climate control performance.
• Durable Construction: Made from high‑quality synthetic fibers that resist moisture absorption and degradation over time.
• Easy Installation: Designed for quick replacement without special tools; fits standard MANN‑FILTER mounting brackets found in many passenger cars.
• Long Service Life: Recommended change interval of 12–15 months or after 10,000 km (whichever comes first) under normal driving conditions.

Compatibility and Vehicle Range

The CU 4007 is specifically tailored for a wide range of passenger vehicles. While it is widely recognized as the standard cabin filter for many MERCEDES‑BENZ models, its dimensions and mounting design allow it to be used in numerous other brands that share similar filter cavities.

Typical Vehicle Models:

• Mercedes‑Benz S‑Klass (W140) – Coupe & Sedan from 1991–1999
• Mercedes‑Benz C‑Class (C140) – Various body styles within the same era
• Other passenger cars with compatible filter housings, including select European and Asian models that use the CU 4007 specification.

Installation Guide

1. Locate the cabin air filter compartment – usually behind the glove box or under the dashboard on the passenger side.
2. Open the compartment cover and remove any retaining clips or screws.
3. Slide out the old filter, noting its orientation (the airflow arrow should point towards the HVAC system).
4. Insert the new CU 4007, aligning it with the airflow direction indicator.
5. Secure the compartment cover and reattach any clips or screws.
6. Reset the vehicle’s filter‑maintenance reminder if applicable.

Performance Benefits

By replacing the cabin air filter with the CU 4007, drivers can experience:

• Improved indoor air quality – reduced pollen, dust and odor levels.
• Enhanced HVAC efficiency – consistent airflow and temperature control.
• Reduced wear on the heating‑ventilation system – less strain from clogged filters.
• Longer overall vehicle comfort and health benefits for occupants.

Maintenance Tips

• Inspect the filter annually, especially after long trips or in dusty environments.
• Replace the filter if it appears visibly dirty or clogged, even if the recommended interval has not yet elapsed.
• Avoid using compressed air to clean the filter; this can damage the media and reduce effectiveness.
• Store spare filters in a dry, cool place to preserve their integrity until needed.
